the INTEL_PSTATE appears to be not suppo...Hi, Mike,<br />the INTEL_PSTATE appears to be not supported for my &quot;Penryn&quot; Core2Duo P8400, neither by hardware nor by the kernel pstate driver? Kernel doesn&#39;t tell anything even if booting with commandline added &quot;intel_pstate=enable&quot;. But I only did a short, i.e. too long, web search that didn&#39;t provide results stating at which generation of Intel cpus this feature was implemented. I assume going from Core i3 to newer.<br /><br />Btw., lowering the dirty_background_* and dirty_* in the vm would follow CK&#39;s approach until 3.7-ck1, setting both *_ratio to 1 in &#39;mm-decrease_default_dirty_ratio-1.patch&#39;, what he dropped since 3.8. (For my old unicore system this &quot;=1&quot; setup was unusable at that former times.)<br /><br />I, personally, will wait some weeks for openSUSE 13.1 and the repos to mature. I had too many bad experiences in the past when upgrading openSUSEs shortly after release date.<br /><br />Best regards, Manuel KrauseAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-28506286128288816482013-11-18T04:07:09.464+11:002013-11-18T04:07:09.464+11:00@Mike ,

Than PSTATE is active.<br /><br />For my vm settings I even must lower it, because writing on an USB thumb drive with ntfs3g still blocks the system.<br />So my /etc/sysctl.conf contains now:<br />vm.dirty_bytes = 209715200<br />vm.dirty_background_bytes = 104857600<br />(Btw. you can use either bytes or ratio values there)<br /><br />cu sysitos<br /><br />PS: Using OpenSuse 13.1 now ;)Mikehttps://www.blogger.com/profile/12391045215046883684noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-75561683585928698602013-11-17T09:28:18.211+11:002013-11-17T09:28:18.211+11:00Mmh, I&#39;m not sure about the X86_INTEL_PSTATE, ...Mmh, I&#39;m not sure about the X86_INTEL_PSTATE, it is activated in my kernel .config since months. But how can I be sure, that it&#39;s active or see the difference, if not? The active driver is acpi-cpufreq, the actual governor is ondemand.<br /><br />Regarding the consensus about the vm tunables, I have to say that I had ported my best-effort settings from -unicore- to my new system -dualcore-: Now seeing that Mike&#39;s (sysitos&#39;) settings are quite better for multicore systems.<br />4 &gt; /proc/sys/vm/dirty_ratio (default openSUSE 12.3 @ 20)<br />2 &gt; /proc/sys/vm/dirty_background_ratio (default -&quot;- @ 10)<br />These seem to eliminate most of the A/V hickups I had with heavy swapping.<br />I still keep my opinion, that it&#39;ll remain a per system, per user job to adjust these for his/her own, what we don&#39;t want for linux future.<br /><br />Best regards, Manuel KrauseAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-45862241405098751012013-11-17T02:25:31.673+11:002013-11-17T02:25:31.673+11:00Hi Chen,

Ubuntu only forgot to reenable the X86_INTEL_PSTATE, which you should use for your Intel Core 2 Duo. It is much better than the other governors and handles the CPU clock speed for its own. But maybe Con could say more, if and how BFS would influence there.<br /><br />PS: As you can read in Phoronix comments to the benchmark test of the better ondemand code in Linux 3.12, these is only in Ubuntu distros without X86_INTEL_PSTATE.<br /><br />CU sysitos<br />Mikehttps://www.blogger.com/profile/12391045215046883684noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-44900869548692276262013-11-16T10:31:46.920+11:002013-11-16T10:31:46.920+11:00Thanks, will try!Thanks, will try!post-factumhttps://www.blogger.com/profile/12098091624630953604noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-5094367322295654362013-11-16T00:26:41.263+11:002013-11-16T00:26:41.263+11:00It&#39;s a pity -- the results don&#39;t show rell...It&#39;s a pity -- the results don&#39;t show relly relevant performance differences in PTS complex system test (with only KDE up in a konsole) on here:<br /><br />-fdefer-pop / -fno-defer-pop<br />159 / 161 Tps - PostMark<br />2810.11 / 2810.07 MB/s - RAMspeed integer<br />3095.08 / 3077.63 MB/s - RAMspeed floating point<br />106.47 / 106.38 s - C-Ray<br />6027.83 / 6003.55 Rps - Apache<br /><br />Best regards, Manuel KrauseAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-82809362029128456472013-11-15T20:32:56.921+11:002013-11-15T20:32:56.921+11:00For those who waiting bfs on 3.12, I have ported b...For those who waiting bfs on 3.12, I have ported bfs-0441 to 3.12, there is 3 conflicts, but seems that are minor ones.
